Year 5 investigate the strength of materials

As part of our materials topic both year 5 classes have been adding different materials to plaster beams to see which one is the strongest.

First we made the beams.

Then we clamped them to the table and hung mass from them on a piece of string. We added 100g at a time and waited.....

....until they broke!

 We made a note of how much mass each beam could hold to find out which one was the strongest.

The preprep science club came down to the science lab today for thier last session of the term

 They learnt about fire

 And saw how carbon dioxide can put out a candle

 And how oxygen makes it burn more brightly

 Time to meet the Methane Mamba

 Its prefectly safe as long as you do as you are told

 and keep under the watchful eye of the experts

Safety is always important 

 Mrs Atkinson even had a go

Year Five test the properties of materials

How much will this bend?

How waterproof is this?

How much light does this reflect?

Does this conduct heat?

How strong is this 

Have we inspired another materials scientist? 

All the airships

If you go down to the sports hall today

You're sure of a big surprise. 

This isn't a crisp packet left over from the teddy bears' picnic

Can you see what it is yet?

Any more guesses?

This is a blimp

It is designed for the egg lifting competition which is part of the Airship Association Model Regatta which is being held here at Brambletye. 

Here's another one

This is a more traditional design for the speed and manoeuvrability competition

Controlled by servos on the fins and driven by propellers. 

Some blimps and one rigid airship

Get down here and see the competition starting very soon

How much energy in a crisp?

This afternoon 8S were calculating the energy in various crisps. 

First weigh your crisp 

Add water to the boiling tube (known volume)

Take the temperature of the water

Burn the crisp under the tube of water

Measure the rise in temperature. 

Do the maths to find the calories then joules then joules per gram. 

The salt & vinegar sticks have the most energy per gram (but the worst taste according to this commentator)

Red cabbage anyone?

Continuing their work with acids an alkalis year seven have made red cabbage indicator. 

First they ground the cabbage with hot water and then filtered it to get rid the yucky (insoluble) bits. 

Then the indicator was tested with many household substances. 

All the results were recorded

Then a range of substances were chosen so that red cabbage indicator could be compared with universal indicator solution. 

Acid > neutral > alkali

Top = universal indicator

Bottom = red cabbage indicator

Year 6 meet the maggots

Testing to see if maggots prefer the dark or the light. 

How sensitive are they?

How fast do they wriggle?

The equipment 

Year 8 use slo-pro on the iPads to find the energy in a spring toy

Year Seven take the acid test

7N test a variety of substances to see if they are acids or alkalis
